replaced screen, bottom microphone no longer works
Text:
I replaced my screen with the ifixit kit. I was pleased that everything seemed to work, then discovered that the bottom microphone doesn't work.
That means no phone unless I use speakerphone, no google assistant, no voice recorder, etc.
I have done nothing other than replace the screen. I was wondering if there could be a problem with the screen connector, that could cause this?
I've tried all the other things on the internet, factory reset, blowing air into the microphone port, making sure microphone isn't disabled in apps, installing third party apps, lots of unlikely desperation stuff.
Does anyone have any ideas?
